Just to jump in on this one. If you proved out wiring then I am thinking it is the control module. The TFI module that you replaced is for the ignition system and the EEC controls injector pulsing. Roy mentioned earlier that the ECM (EEC is the same thing) controls the injectors so we need to check the pin 58 at the EEC to see if we have voltage. I assume we don't. If not, and you have no codes, then I suspect the control module is the issue.
